Hybrid Tea rose plant named `Selgallia`

ABSTRACT

A new rose variety of the Hybrid Tea class, characterized by its continuous good production of apricot colored flowers having good bud size in relation to the size of the stem, said flowers being borne singly on upright stems on a bush of medium height (100-130 cm.), and that is especially well suited for growing in mountainous countries (typical growth conditions such as light intensity, day length, and seasonal effects), such as in Latin America. The cultivar is grown mainly under cover.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct variety of roseplant of the Hybrid Tea class, which was discovered by me as being anaturally occurring mutant of the variety `Marjan`.

The primary objective of this breeding was to obtain a new large typerose having good bud size in relation to its stem, in different colors.Among the novel characteristics possessed by the new variety whichdistinguish it from its parent and all other varieties of which I amaware are:

(1) The apricot color of the flower.

The other distinctive characteristics, which distinguish it from allother varieties of which I am aware, already possessed by its parent areretained:

(2) A very large flower and flower bud.

(3) Rapid flowering cycles.

(4) Suitabiliy for growing in Latin America.

(5) Good bud size in relation to its stem length.

Asexual reproduction of the new rose variety by cutting and graftingusing R. canina `Inermis` as rootstock, as performed in a greenhouse inQuito, Ecuador, shows that the aforementioned characteristics anddistinctions come true to form and are established and transmittedthrough succeeding propagations.

BRIEF DESCRIPTION OF THE DRAWINGS

The new variety of rose plant is illustrated by the accompanyingphotographic illustrations, of which:

Sheet 1 shows a full face view of the flower; and

Sheet 2 shows typical specimens of the vegetative growth and flowers ofthe new variety in different stages of development and as depicted incolor as nearly true as it reasonably possible to make the same in colorillustrations of this character.

The following is a detailed description of this new variety, with colorterminology in accordance with The Royal Horticultural Society ColourChart (R.H.S.C.C.). The terminology used in the color description hereinrefers to plate numbers in the aforementioned color chart e.g. "55C" isplate "55C" of The Royal Horticultural Society Colour Chart.
